Plenty of people still happily drive a Peugeot or Citroën built between 2004 and 2010. These cars are often reliable, comfortable, and mechanically sound. The biggest downside usually isn’t the engine or the suspension, but the original RD4 radio. No Bluetooth means no hands-free calling, no Spotify, no podcasts, and no navigation voice instructions through the speakers. That leaves you choosing between replacing the entire head unit or living with cables.
The Biurlink RD4 Car Radio Bluetooth 12Pin AUX Adapter offers a much smarter alternative. This compact module connects directly to the original RD4 radio and adds Bluetooth 5.0 plus a microphone. You keep the factory look of your dashboard, but gain modern functionality. And the price is surprisingly low compared to replacing the whole radio system.

How it works in everyday use
After installation, you pair your phone with the module via Bluetooth. On the radio, you simply select AUX. From that point on, music, navigation instructions, and phone calls play through the car’s speakers. The included microphone makes hands-free calling possible, which is both practical and safer while driving. With an average rating of about 4.3 out of 5 based on 22 reviews, users generally describe the performance as good for the price.
One thing to be aware of: a few users mention that on certain cars, such as the Peugeot 407, the connector pinout may need a small adjustment. This isn’t common, but it’s good to know in advance. If you run into issues, I’m happy to help — as long as you reach out.

Price, VAT included, no hidden costs
The price is around €5.69 and includes VAT. This is important, because in the past it worked differently. Years ago, you might receive the package and then get hit with extra VAT, customs, or administrative fees. Today, AliExpress usually handles VAT upfront. The amount you see at checkout is the final amount, with no surprise charges afterwards.
Watch out for “unknown” websites
You’ll often see the same type of adapter sold on obscure websites for €20–€40. Returns on those sites are often difficult, expensive, or not possible at all. On AliExpress, returns are usually easier and often free. My advice is simple: never pay more than the AliExpress price and order via a reliable link like this one:

How this website started
This website grew out of the countless questions people asked on the old VraagAlex website about AliExpress orders: compatibility issues, returns, and shipping problems. I still do the same thing today — helping people make sense of it all.
“We are not the official AliExpress customer service, but we are happy to help you with questions about this product or your order.”
